# -*- coding: utf-8 -*- """ Receive-side station emulator for connect frame tests over a high quality simulated audio channel. Near end-to-end test for sending / receiving connection control frames through the TNC and modem and back through on the other station. Data injection initiates from the queue used by the daemon process into and out of the TNC.
